Compare JavaScript Object-Array Property with String

Question

Hello I have a quick question regarding my javascript array:

var firstrecord = {
    name: 'Luca',
    age: '19'
};
var secondrecord = {
    name: 'Hans',
    age: '25'
}

var myArray = [];
myArray.push(firstrecord,secondrecord);

Alright, now I have a var SearchString = "Lu".

What I'd do:

for (var i = 0; i < myArray.length; i++) {
    if (myArray[i].[name].IndexOf(SearchString, i)) != 1){
    return myArray[i];
    }
}

But this doesn't work. Is there any solution to this problem ?

Update: indexOf != IndexOf Reminder to self.. first lookup the use of such functions before misusing them. :)

It's stylistically unorthodox to use a leading upper-case letter for the names of simple variables. Generally upper-case is reserved for constructor function names. — Pointy

Two errors here:

if (myArray[i].[name].IndexOf(SearchString, i)) != 1){

First, it's .indexOf(), lower-case "i". Second, you need just one or the other of . and [ ]:

if (myArray[i].name.indexOf(SearchString, i)) != 1)

Now, I don't know what it is you're trying to do here, but passing i as the second parameter of .indexOf() doesn't make much sense to me, and neither does comparing the return value to 1. If what you want to do is see if the search text appears at the start of the name, you'd do this:

if (myArray[i].name.indexOf(SearchString) == 0)

That was fast! You got me, where I'm passing the i, that was not correct, got that from another try. Your solution works like a charm :)
